Abstract
The invention relates to a hole depth fast test tool which comprises a measuring device, a fastening sleeve, a conical table, a mandrel and a locking screw. The mandrel penetrates through the longitudinal axis of the conical table in a connecting manner; the locking screw is arranged at the position, on one side of the mandrel, of the side face of the conical table; the tail end of the locking screw abuts against the mandrel; the other end of the mandrel is provided with the measuring device fixedly connected with the conical table through the fastening sleeve. The hole depth fast test tool has the advantages of being high in measuring precision, convenient to use, high in efficiency and the like.
Description
Technical field
The present invention relates to cubing technical field, particularly a kind of hole depth Quick detection tool.
Background technology
In machining, check the degree of depth in the hole on part, the general universal check tools such as vernier caliper that adopt are measured.In order to improve accuracy of detection, existing employing diameter is that the steel ball of 8 millimeters is put into the way that then center pit adopt height gauge to detect and carried out inspection center's hole depth.Although adopt height gauge to detect can improve precision, error is still comparatively large, and this way efficiency is lower.In addition, the Measuring Time required for universal check tool measurement is long, in production line is produced or produced in enormous quantities, requires that carrying out hole depth inspection to each product has certain difficulty.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of measuring accuracy high, easy to use, the hole depth Quick detection tool that efficiency is high.
Realize technical scheme of the present invention as follows:
A kind of hole depth Quick detection tool, comprise measurement mechanism, fixing sleeve, frustum, axle and lock-screw, described axle is established and is connected to frustum longitudinal axis center place, and the frustum side of axle side is provided with lock-screw, end and the axle of lock-screw are inconsistent, and axle opposite side is provided with the measurement mechanism be fixedly connected with frustum by fixing sleeve.
Described measurement mechanism comprises survey table, gauge head and measuring staff, and survey table is fixed on measuring staff upper end, is connected between measuring staff and gauge head by spring, and the head of gauge head is placed in frustum outside, and advantage is easy accessibility, convenient operation, and reading is accurate.
Described survey table is dial gauge or clock gauge, and advantage is that degree of accuracy is high.
Described mandrel bottom is for being set to conical surface chamfering, and advantage is convenient to coordinate preferably with bottom hole, reduces error.
Have employed above-mentioned scheme, the effect being positioned by axle and lead, the axle of this cubing is inserted in measured hole by hand-held frustum, carry out back rotation, mandrel bottom is coordinated preferably with bottom surface, hole, the numerical value of such measurement is comparatively accurately stable, frustum plays the effect of handle, because this cubing adopts comparative measurement method, be usually equipped with calibrating device, the part of measurement is different, calibrating device is also different, will adjust the length of axle like this, set nut plays the position-limiting action of center roller, and axle can be adjusted by set nut; The precision that such cubing is measured is high, easy to use, and efficiency improves greatly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In accompanying drawing, 1 is frustum, and 2 is axle, and 3 is set nut, and 4 for surveying table, and 5 is measuring staff, and 6 is gauge head, and 7 is fixing sleeve, and 8 is spring.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
As Fig. 1, a kind of hole depth Quick detection tool, comprise measurement mechanism, fixing sleeve 7, frustum 1, axle 2 and lock-screw 3, described axle 2 is established and is connected to frustum 1 longitudinal axis center place, frustum 1 side of axle 2 side is provided with lock-screw 3, and end and the axle 2 of lock-screw 3 are inconsistent, and the opposite side of axle 2 is provided with the measurement mechanism be fixedly connected with frustum 1 by fixing sleeve 7.
Described measurement mechanism comprises survey table 4, gauge head 6 and measuring staff 5, and survey table 4 is fixed on measuring staff 5 upper end, is connected between measuring staff 5 and gauge head 6 by spring 8, and the head of gauge head 6 is placed in frustum 1 outside, and advantage is easy accessibility, convenient operation, and reading is accurate.Described survey table 4 is dial gauge or clock gauge, and advantage is that degree of accuracy is high.For being set to conical surface chamfering bottom described axle 2, advantage is convenient to coordinate preferably with bottom hole, reduces error.
When detecting, first the axle of cubing being inserted in the hole of calibrating device, after micro-turn, reading stable indicating value from surveying table, immediately to the zeroing of survey table; When measuring part by this cubing again, spend the deviate of actual grade that the value is exactly endoporus and calibrating device depth value from survey table.
